high quality powder coating white pergolar aluminum profile

Aluminum alloy spray powder for outdoor sunshade racks needs to meet a series of requirements to ensure its weather resistance, corrosion resistance and aesthetics for long-term use in outdoor environments. The following are the main spray powder requirements:

1. Weather resistance requirements:

UV resistance: Outdoor sunshade racks are often exposed to the sun, and spray powder needs to have excellent UV resistance to prevent color fading and surface powdering.

Corrosion resistance: Spray powder should have good corrosion resistance and be able to resist corrosion factors such as chemicals, rain, salt spray in the atmosphere, especially at the seaside or in areas with heavy industrial pollution.

2. Color and appearance requirements:

Color stability: The color after powder spraying should be stable and lasting, not affected by climate and sunlight, to ensure long-term good appearance.

Color selection: Provide a wide range of color options to meet the design needs of different customers and projects, including metallic luster, matte and glossy effects.

3. Spraying uniformity and quality control:

Uniformity: Powder spraying should evenly cover the surface of aluminum alloy to avoid spots or unevenness, and ensure the consistency and beauty of the overall appearance.

Coating thickness: Ensure that the thickness of the powder coating meets the design specifications, which can provide sufficient protection layer without affecting the assembly and use of the product.

4. Environmental protection requirements:

No VOCs (volatile organic compounds): The emission of volatile organic compounds should be minimized or avoided during powder spraying, in line with environmental protection standards and regulatory requirements.

5. Testing and certification:

Weather resistance test: Conduct weather resistance tests such as salt spray test and UV exposure test to verify the performance of powder coating under different environmental conditions.

Quality control: Implement strict quality control measures, including inspection of raw materials, monitoring of production process and inspection of finished products, to ensure the quality stability and reliability of powder spraying.

Through the above powder spraying requirements and control measures, our factory can ensure that the outdoor sunshade aluminum alloy has good weather resistance, appearance effect and environmental adaptability after spraying, extend its service life and enhance the market competitiveness of the product.
